Common Gases

The purpose of this page is to discuss some common gases and their properties, both chemical and physical. These are gases that can be created in the lab using fairly common reagents. The reaction and methods of preparation will also be discussed.

Carbon Dioxide

Carbon dioxide can be produced in several ways. The video below shows the decomposition of a carbonate.

Copper(II) carbonate is heated in a beaker so an environment of carbon dioxide is created as it decomposes. A lit piece of magnesium is placed inside and reacts strongly with the carbon dioxide. In the combustion of hydrocarbons, the presence of carbon dioxide (a product of the combustion) will extinguish a flame. Here, the carbon dioxide increases the vigor of magnesium's oxidation.

Nitrogen Dioxide

Oxygen

After heating potassium chlorate, a hot
oxygen environment is produced. This allows for the spontaneous combustion of a Peep, which is made of
sucrose. The decomposition of a metal chlorate will always yield a metal chloride and oxygen gas. Potassium chlorate and sodium chlorate are commonly used for this purpose.

Chemistry-Reference.com provides you with capsules on many topics in chemistry. Additionally, there are reference tables and profiles of every element and thousands of compounds. Use the interactive menu bar located above to get started. Many online periodic tables only provide basic information for a particular element. Here, a full profile of the element's physical properties, chemical behavior, isotopes, and electron structure are provided. For further reading and reference, list of sources can be found at the conclusion of each page.
